SPOKANE — Gonzaga forward Kelly Olynyk said Friday he will skip his senior season to enter the NBA draft.

The decision caps a whirlwind season in which Olynyk went from afterthought to All-America selection and led Gonzaga to the top spot in The Associated Press poll for the first time in school history.

The 7-foot forward said he made the final decision Thursday night and informed coaches and teammates. He said the big factor was his desire to play in the NBA.

"In the end, it's something you've dreamed about since you were a little kid," Olynyk said Friday, which was his 22nd birthday

Olynyk, a native of Canada, averaged 17.8 points and 7.3 rebounds while shooting 63 percent from the field. He led Gonzaga to a 32-3 season that ended when the top-seeded Bulldogs were upset by Wichita State in the third round of the NCAA tournament.

"We are very proud of what Kelly was able to accomplish at Gonzaga both on the court and in the classroom," coach Mark Few said. "We wish him all the best in his next challenge."

Olynyk was a reserve player his first two seasons, then redshirted after his sophomore year to work on his body and his game. Not many people expected him to put together an All-America season for what has been called the best Gonzaga team in program history.

"Nine months ago this wasn't what I envisioned for today," Olynyk said. "It came quicker than I expected, and I've got to capitalize."

Olynyk spent most of his childhood in Toronto and said he would love to play for the Raptors. He has been told he might be drafted as high as the middle of the first round.

"It's all speculation," he said.

Olynyk became the first Gonzaga player since Austin Daye to leave early for the NBA. Daye came out following his sophomore year and was a first-round choice by Detroit.
